IMPROVEMENT IN PLOUGHS.

' EH12 l1th1lit mam-t it in the haters time no making not at in stun.

TO ALLWHOM IT MAY CONCERN: I

Be it known that I, ALEXANDER WRIGHT, of the city and county ofAllegheny, in the State of Pennsylvania, have invented a new and-usefulImprovement in Ploughs; andI do'hercby declare that the following is afull and exact description thereofl reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon.

The nature of my invention consists in constructing a plough which willanswer the double purpose of a hill-side and a level-land plough, and soarranged that the face of the mould-board 'and'sh'are may be turned fromthe right to the left-hand side of the plough-beam by'sim-ply turningdown sideways the beam and handles of the plough, and then securing themould-board withvrelation to the beam and handles by means of a lever,the whole being constructed, arranged, and, operating in the mannerhereinafter described.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. In the accompanyingdrawings, which form 'part of my specification- Figure 1 is aperspective view of my improvement in ploughs, and represents the faceview of the mouldboard and share when they are turned to the right-handside of the beam.

Figure 2 is a perspective view of the same, and represents theback ofthe mould-board and share, with their'faces turned to the left-hand sideof the beam.

In the drawings, A represents the mould board and B represents theshare, both of which present double workingedgesand faces. Themould-board and share are, by bolts, suitably secured to the block orpiece marked R, which is pivoted to the land-side G at the point marked1, (se e fig. To the back of the mouldboard A are attached braces 2,3,'and 4,\Vhl0l l are connected to an arm, 5, which is at its lower endpivoted to the land-side G. On the back of the mould-board A, near theupper and back ends, are two projections, 0 and 0, which are providedwith openings for the end of the lever m, which is held to the side ofthe beam D by means of the piece marked f. The upper end of the lever mis held by thepiece x, on thebrace n, for the handles e.

As the form, construction, and arrangement of the several parts of myimprovement, and the relation that these parts bear to each other, willreadily be understood by the skilful mechanic by reference to theaccompanying drawings, Iwill therefore, without further description ofits construction, proceed to describe its operation, which is asfollows: When I desire to turn the face of the mould-hoardand share tothe right-hand side of the plough-beam, I draw the lower end of thelever m out of the projection 0, and then turn the handles e and beam Ddownsideways, and then place the lower e nd oi' the lever m in theprojection 0, and then raise up the handles and beams; and whenI desireto turn the face of the mould-hoard to-jthe left-hand side of the.plough-beam, I draw the lower end of" the lever out of the projection o,and then turn the handles and beam down to the right, and place thelower end of the lever m in theprojection o, and then raise upthehandlcs and beam to their proper position. v I I Ihe advantages of myimprovement in ploughs consist in theiease and facility of changing theposition of the mould-board and share. By the peculiar construction ofthe plough, I' obtain a central draught, which Ilsa great desideratnm ina pl'ough,l and give to the farmer a plough which will answer the doublepurpose of hill-side and level-land plough. I

Having thus described the nature, construction, and operation of myimprovement, what I claim as of my invention is- V A plough,constructed, arranged, and operating substantially as herein described,and for the purpose set forth.

ALEXANDER WRIGHT.
